2-(Naphthalene-2-sulfonamido)-3-phenyl-propanoic acid.

ABSTRACT: In the title compound, C(19)H(17)NO(4)S, the phenyl ring and the naphthalene ring system are oriented at a dihedral angle of 4.12?(2)° and the mol-ecule adopts a U-shaped conformation. The C(c)-C-N-S (c = carb-oxy) torsion angle is 90.98?(15)°. In the crystal, mol-ecules are linked by O-H?O and N-H?O hydrogen bonds, resulting in (100) chains incorporating centrosymmetric R(2) (2)(14) and R(2) (2)(10) loops. Weak aromatic ?-? stacking is also observed [centroid-centroid separations = 3.963?(2) and 3.932?(2)?Å].

Project description:The complete mol-ecule of the title compound, C30H29N3O5S2, is generated by a crystallographic twofold axis: the O atom and NH group attached to the central benzene ring are statistically disordered. The dihedral angle between the naphthalene ring system and the central benzene ring is 52.99 (6)°, while the pendant naphthalene ring systems subtend a dihedral angle of 68.17 (4)°. An intra-molecular C-H⋯O hydrogen bond closes an S(6) ring. In the crystal, the mol-ecules are linked by weak C-H⋯O hydrogen bonds.

(2E)-2-(2-Phenyl-hydrazin-1-yl-idene)propanoic acid.

Project description:The 13 non-H atoms comprising the title compound, C(9)H(10)N(2)O(2), are close to planar (r.m.s. deviation = 0.140?Å), with maximum deviations of 0.292?(1) and 0.210?(1)?Å to either side of the least-squares plane exhibited by the hy-droxy and carbonyl O atoms, respectively. The observed conformation is stabilized by an intra-molecular O-H?N hydrogen bond. The conformation about the N=C double bond [1.2909?(16)?Å] is E. The hy-droxy OH group also forms an inter-molecular hydrogen bond to a carbonyl O atom, and the amine H atom similarly forms an N-H?O hydrogen bond to a second carbonyl O atom. The result is the formation of a double layer with a flat topology. Layers stack along the a-axis direction connected by C-H?? inter-actions.

3-(1H-Indol-3-yl)-2-(2-nitro-benzene-sulfonamido)-propanoic acid including an unknown solvate.

Project description:In the title compound, C(17)H(15)N(3)O(6)S, which crystallized with highly disordered methanol and/or water solvent mol-ecules, the dihedral angle between the the indole and benzene ring systems is 5.3?(2)°, which allows for the formation of intra-molecular ?-? stacking inter-actions [centroid-centroid separations = 3.641?(3) and 3.694?(3)?Å] and an approximate overall U-shape for the mol-ecule. In the crystal, dimers linked by pairs of N(s)-H?O(c) (s = sulfonamide and c = carboxyl-ate) hydrogen bonds generate R(2) (2)(10) loops, whereas N(i)-H?? (i = indole) inter-actions lead to chains propagating in [100] or [010]. Together, these lead to a three-dimensional network in which the solvent voids are present as inter-secting (two-dimensional) systems of [100] and [010] channels. The title compound was found to contain a heavily disordered solvent mol-ecule, which could be methanol or water or a mixture of the two. Due to its uncertain nature and the unresolvable disorder, the data were processed with the SQUEEZE option in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155], which revealed 877.8?Å(3) of solvent-accessible volume per unit cell and 126 electron-units of scattering density or 109.7?Å(3) (16 electron units) per organic mol-ecule.. This was not included in the calculations of overall formula weight, density and absorption coefficient.
